A system and method for detecting a hands-off state of a steering wheel may include acquiring, by a controller, a steering torque, a steering angle and a steering angular speed while driving of a vehicle, determining, by the controller, a variance value of the steering angular speed through cumulation for a designated time, determining, by the controller, a difference value between a steering angular speed estimated through a steering system model determined on an assumption that the steering wheel is in the hands-off state and a measured steering angular speed through cumulation for a designated time, when the variance value of the steering angular speed is less than a first threshold value, and divisionally determining, by the controller, whether or not the steering wheel is in the hands-off state or in the hands-on state according to the difference value between the measured and estimated steering angular speeds.

A sensor for measuring shear force and a dummy for testing a vehicle using the same are provided herein. A sensor for measuring shear force which is configured to quantitatively accurately measure shear force applied to a human body who sits on a vehicle seat, and a dummy for measuring shear force using the sensor are provided, wherein the sensor for measuring shear force includes an upper block, an intermediate block and a lower block and is configured such that a first strain gauge is mounted upright between the upper block and the intermediate block and a second strain gauge is mounted upright between the intermediate block and the lower block so that the shear force can be accurately measured without being affected by horizontal tensile force.
